Electromagnetic Vibrating Feeders

Jeffrey Rader’s EF and HP electromagnetic feeders use controlled, high-frequency vibration for efficient material handling across industries like aggregates, coal, minerals, and chemicals. With low maintenance and positive drive components, they offer reliable, quiet operation, reducing energy costs and ensuring long service life. These feeders feature sub-resonant tuning, vibration-absorbing springs, and NEMA 12-compliant controllers for precise control and soft starts. Their design flexibility, high reliability, and ease of maintenance make them ideal for various applications, delivering exceptional capacity and material control with components made in North America.
